James Clerk Maxwell, Scottish physicist
James Clerk Maxwell (1831-1879), Scottish physicist. Maxwell's works cover a wide area of science, and he is regarded as one of the finest minds of the 19th century. His major work was on light and electromagnetic waves. He showed that oscillating charges produced waves in an electro- magnetic field, which had the same velocity as light. This led him to predict the existence of other forms of radiation, such as radio waves. His equations introduced the value c for the speed of light. He also worked on the motions of molecules in a gas, and showed that Saturn's rings must be composed of numerous particles.

Tornadic supercell thunderstorm, USA
Tornadic supercell thunderstorm over fields. A supercell thunderstorm is a severe long-lived storm within which the wind speed and direction changes with height. This produces a strong rotating updraft of warm air, known as a mesocyclone, and a separate downdraft of cold air. Photographed near Gove, Kansas, USA, on 31st July 2009.
